SynthesisA preparation method of 1-[[(6R,7R)-7-[[(2Z)-2-(2-AMino-4-thiazolyl)-2-[[2-(1,1-diMethylethoxy)-1,1-diMethyl-2-oxoethoxy]iMino]acetyl]aMino]-2-carboxy-8-oxo-5-thia-1-azabicyclo[4.2.0]oct-2-en-3-yl]Methyl]pyridiniuM Inner Salt: add trichloromethane 520ml in a clean and dry four-necked reaction flask, add tert-butanol 30ml, and lower the temperature to 0-5. Add 7-APCA70g, tert-butyl ester 105g, control the temperature dropwise addition of triethylamine, adjust the PH to 7.0-9.0. Control the temperature 0-10 reaction 20-24 hours. After the reaction, add 150ml of pure water, stirring for 1-2 hours, separated from trichloromethane. Drops of isopropanol in the liquid precipitated ceftazidime tert-butyl ester, 0-10 stirring to raise the crystal for 2 hours. Filtered, washed with isopropanol, dried to obtain ceftazidime tert-butyl ester dry product. Weight yield: 145%, purity 98.9%.
